There is more of it this year.....the trees are bigger.
Seriously, I think this on and off winter/spring that we had slowed things down and everything dumped their pollen during a shorter period of time to get ready for summer. "They" say that heavy pollen falls mean more acorns and pine cones for the squirrels to lay up nuts and seeds for a cold, cold winter. In zone 8b/9a, the pines seem to be finished and the oaks just getting started.
